Pick up a Mark 5HD and you'll feel the difference: it's up to 20ozs lighter than other scopes in its class. Get behind one and you'll see the difference, from the superior edge-to-edge clarity and extreme low-light performance. With three revolutions of elevation adjustment, the Mark 5HD was built to max out the performance of the latest long-range rifles and ammo. Ergonomically designed with more tactile, audible click adjustments, larger numbers, and a high-speed throw lever so you can put accurate fire downrange faster
